CNC machining is becoming popular, especially among manufacturers. Most people have heard about CNC machining, but not all of them can explain how the technology works. CNC machining is an abbreviation for Computer Numeric Control Machining. The technology is a manufacturing process that uses computers to handle machine tools such as routers, grinders, and CNC mill parts. Experts use Computer Aided Design (CAD) software to create a design. The design is then turned into numeric using a computer. These numbers serve as coordinates and manage the work of a carefully designed cutter. This article explores five things that you did not know about CNC machining.
1. Programming–Professionals use the G-code language to program CNC machines. Programmers use the code to manipulate every movement the tool makes during the manufacturing process. The G-code instructions control the speed and positions the cutting equipment.
2. It begins with CAD–The whole process starts with either a 2D CAD or a 3D CAD drawing model. The professionals then derive the G-Code from this software and run a trial to test the program. This process is known as “cutting air,” and it is crucial to prevent any mistakes that could damage the work-piece or the cutting tool. If the test is a success, the experts continue to run it on the real part.
3. CNC offers precision and repetition–You can use CNC to create complex 3D shapes as a single unit. Compared to manual machining, CNC allows greater accuracy. The best thing is that the process is repeatable. You can use the same CNC program to manufacture multiples of the same part.
